Small boats leave the harbour throughout the day on two to three hour trips out into the strait. Sightings of pilot whales and bottlenose dolphins are almost guaranteed; sperm whales, fin whales, and even orcas pass through at certain times of year. Operators range from quiet sailboats to larger catamarans; the smaller ones are better for actually hearing the whales blow.
Avoid any boat that approaches the animals closely or charges them at speed — responsible operators keep a respectful distance, cut engines, and let the whales come to them. Prices are typically 25 to 40 euros for the standard trip. Mornings tend to be calmer than afternoons.
